CVE-2021-32957Network attack vector

Remote binary execution via executable path hijacking

Published Apr 1, 2022 · Updated Apr 16, 2025

Uncontrolled executable search in MDT Software AutoSave and A4SP allows remote attackers to execute attacker-chosen binaries. A process-information function runs several commands, summarizes their results in XML, and supplies an executable path in a way that permits binary hijacking. The function is reachable without authentication; successful exploitation changes execution or application-controlled data, with no reported disclosure or service interruption.
